Mine diamonds are increasingly confronted
with reality: repeated strikes in third world mines and denunciation of working conditions, expulsion of mining companies from mining countries, environmental impact of open pit mines, blood diamonds, countries in civil war (payment counterpart for weapons of war) and lack of traceability of stones.
Although progress has been made, the origin and traceability of stones are still difficult to guarantee 100%.
While extraction is decreasing (-50 % by 2035), demand for jewelry is increasing by 4 % per year.
The alternative solution which
is a real conviction is obviously
the lab-grown diamonds.
A state-of-the-art technology:
We design our Plasma CVD reactors to grow the highest quality diamonds.
Our method consists in creating a plasma composed of molecular hydrogen and methane. The plasma discharge is established in a microwave resonant cavity and is responsible for the creation of the keys species for diamond growth, i.e. H atoms and C containing radicals. These plasmas are ionized gas composed of electrons, ions and electronically excited species that confer nice colors as those observed in northern Lights.
Lab grown diamonds are absolutely identical to mine diamonds except their origin. They are composed as mine diamonds of carbon atoms ordered in a specific crystalline structure. They grow mostly as fast as mine diamonds but they are extracted from their growth medium in a shorter time.
In Diam Concept company, we grow diamond using a plasma miming what happens in the Universe.

Diam Concept has been created in May 2016 by Alix Gicquel. She is worldwide recognized after she went up the first team working on “plasma for diamond growth” in France in 1990. She has published more than 170 scientific papers and 7 patents.
Diam Concept conceives plasma reactors and controls diamond growth. Diam Concept addresses to high jewelry.
In 4 to 5 years, Diam Concept should have about twenty reactors to produce more than 10,000 stones a year.
Diam Concept benefits from the support of several institutions and enterprises who have provided us with their expertise, time and/or financial support.
Great distributors and jewelers trust Diam Concept know-how and the quality of its diamonds.
We look forward
